FREDERICK M. MEES, OF CHICAGO, ILLINOIS TEMPORARY BINDER.

SPECIFICATION forming part of Letters Patent N 0. 642,800, dat d, February 6, 1900.

To all whom it may concern.-

Be it known that I, FREDERICK M. MEEs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois,have invented a new and useful Improvement in Temporary Binders, of which the following is a specification.

My invention relates to an improvement in temporary loose-sheet binders of .the class in which the retaining mechanism is between covers connected at one end by a back and involves filing-pins adjacent to one cover on which to confine the sheets at perforations provided in them near their edges and tubular filing-pins adjacent to the other cover for telescoping with the pins thereon by closing the covers and to be separated by opening the covers.

My object is to provide a novel construction of temporary binder in the class referred to, rendering the mechanism and operation peculiarly simple to enhance the convenience of use of the binder.

Referring to the accompanying drawings, Figure 1 shows myimproved temporarybinder in end elevation with the covers laid open, but with the binding mechanism closed. Fig. 2 is a longitudinal section of the same with the binding mechanism, as well as the covers, open; Fig. 3, a plan view of the binder in the condition in which it is represented in Fig. 2; Fig. 4, a broken longitudinal sectional view of a binder as shown in Fig. 1, but on a larger scale, and with the filing-pins in vertical position; and Fig. 5, a transverse section taken lengthwise through the back on a line between the locking-finger and its pivotal controlling-cam on Fig. 3 and viewed toward the left on said figure.

A and A are stiff covers flexibly connected or hinged at adjacent ends, respectively, to an edge of the back B, of general U shape in cross-section, formed in two separate longitudinal rigid sections a and a, L-shaped in cross-section and lined with metal plates, as shown at b and b, which stiifen them. On the edges of the metal linings b b where the covers join the backs are formed tubular heads 0 c, in which, respectively, are confined rock-shafts d and d. From opposite sides of the transverse center of the shaft d there extend at right angles to it to rock with it and through elongated slots f f in the tubular bearing-head c filing pins e e, and coincident with these pins, respectively, are provided on the shaft d to extend at right angles to and rock with it tubular filing-pins e 6, pro-' ject-ing through transverse elongated slots f f in the tubular bearing head 0. The outer ends of the slots f f afiord stops for the filing-pins against turning them backward unduly far on opening the binder, as hereinafter described.

The horizontal portion of the lining-plate 1) projects to the dotted line as in Fig. 3 beyond the adjacent edge of the section of the back B, which it lines, and contains at intervals slots g 9, extending transversely inward from its outer edge. The corresponding portion of the metal lining 1) projects to the dotted line as in Fig. 3 beyond the adjacent edge of the section of the back B lined by it and is raised slightly above the surface of that section to overlapthe plate I), which telescopes with it to enable the back-sections to be pushed together and pulled apart, as hereinafter described, in which they are guided by the slots 9 g,' embracing the screws h h, coincident with them, which fasten the lining b to the back-section.

Along opposite ends of the horizontal portion of the lining bthere project at right angles thereto guide-fianges'i ifor the corresponding edges of the horizontal portion of the plate I), just above the plane of which, confined in the guide-flanges, are longitudinal racks k and Z. Pivotally fastened to the horizontal portion of the lining b, at opposite sides of its transverse center, are the sections of cog-wheels k and Z, respectively meshing with the racks k and Z and connected together from opposite sides of their pivots by a link on to insure their uniform turning. In the cog-wheel section his shown an arc-shaped slot n, into which a stud 17. projects upward for guiding and steadying the wheel in the movements about its pivot.

A locking device is shown comprising a spring-pressed pivotal finger 0, having teeth 0 at one end to engage with those of the wheel-section Z to prevent movement-0f the filing-pin-actuating mechanism and consequent separation of the filing-pins. The locking-finger is, however, normally maintained out of engagement with the wheel-sectionl by a rotary cam-stud p, journaled in the backsection a and projecting through the plate I). hen the flat side of the stud is adjacent to the locking-finger, its controllingspring forces its teeth out of engagement with those of the adjacent cog-wheel, and by turning the stud to present its rounded surface to the finger it forces and holds the latter into engagement with the cog-wheel teeth to lock the filing-pin-controlling mechanism.

For convenience in turning the cam-stud from the outer side of the back 13 holes are provided in the outer end of the stud at'opposite sides of its center, as shown in Fig. 5, to receive the prongs of a suitable key, such as it is common to provide for similar uses.

\Vhile the parts and Z are shown and described as wheel-sections, they may be entire, the only purpose of their mutilation being to save metal.

The operation is as follows: To reduce the binder to its condition for filing perforated sheets 0, the covers A A are opened, and the user employs his hands to spread apart the sections of the back B, thereby causing the movement of the racks 7t Z to turn the cogwheels on their pivots and withdrawing from each other the filing-pins e and e. The pins 2 are then turned to upright position for facility in filing upon them sheets 0 at their perforations, which coincide with the pins. After adjusting a sheet or sheets on the pins e the covers are closed to bring the pins e and e coincident with each other across the back B, when the user presses together the two sections of the back, thereby telescoping the pins 6 into the tubular pins (2, which latter thereby pass through the perforations in the sheets.

By means of my improvement access to any particular paper orpapers filed in the binder for removal and reinsertion thereof is rendered very convenient. Vhen the binder is partly or entirely filled with sheets 0, their weight when opened upon the opposite covers for such access and when the back-sections and cooperating filing-pins have been drawn apart turns the pins into the upright position convenient for filing, and by bearing against the filing-pins in closing the covers the sheets turn the opposite pins, as indicated by the dotted lines between the pins in Fig. 2, into coincidence across the back to adapt them to telescope by pressing together the sections of the back 13.

Itwill be noted that the filing-pins on each side of the longitudinal center of the back are supported on a rock-shaft. This is an important feature of my improvement, since thereby the filingpins on each shaft are adapted to be brought into upright position for convenience in filing sheets on either set of the pins, for enabling the filed sheets to be separated for access to any sheet between them and turned to lie flat on the opposite covers, whereby the reading matter on either side of the sheet shall be fully presented to view.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a temporary binder, the combination of a back formed of longitudinal sections connected to adapt them to be spread apart and forced together, covers hinged to the outer edges of said back-sections, two rock-shafts, one journaled on each back-section near its outer edge, and filing-pins carried by said rock-shafts to cause each pin on one rockshaft to coincide with another with which it telescopes 011 the other rock-shaft, whereby spreading apart said back-sections withdraws from each other the coincident filing-pins to enable them, by turning both rock-shafts, to be turned into upright position, and forcing together said back-sections causes the opposite coincident filing-pins to telescope one another, substantially as described.

2. In a temporary binder, the combination of a back formed of rigid longitudinal sections of rectangular cross-section, reinforced with metal lining-plates projecting and mutually overlapping beyond the adjacent edges of said sections, covers hinged to the outer edges of said back-sections, two rock-shafts, one journaled on each back-section near its outer edge, and filing-pins on said rock-shafts adapted to telescope one with the other by turning them into alinement across the back and forcing the back-sections together, and to be separated to assume upright positions by spreading apart said back-sections, substantially as described.

3. In a temporary binder, the combination of a back formed of connected longitudinal sections adapted to be spread apart and forced together, covers hinged to the outer edges of said back-sections, two rock-shafts, one journaled on each back-section near its outer edge, filing-pins on said rock-shafts adapted to telescope one with the other by turning them into alinement across the back and forcing the back-sections together, and to be separated to assume upright positions by spreading apart said back-sections, racks on opposite ends of one back-section and cog-wheels pivoted on the other back-section to engage said racks, substantially as described.

' 4. In a temporary hinder, the combination of a back formed of connected longitudinal sections adapted to be spread apart and forced together, covers hingedto the outer edges of said back-sections, rock-shafts journaled near the outer edges of the back and carrying filingpins adapted to telescope one with the other by turning them into alinement across the back and forcing the back-sections to gether, and to be separated to assume upright positions by spreading apart said back-see tions, racks on opposite ends-of one backsection, cog'wheels pivoted on the other backsection to engage said racks, and a link connecting said cog-wheels from opposite sides of their pivots, substantially as described.

5. In a temporary binder, the combination of a back formed of connected longitudinal sections adapted to be spread apart and forced together, covers hinged to the outer edges of said back-sections, two rock-shafts, one journaled on each back-section near its outer edge,

tually overlapping beyond the adjacent edges of said sections, covers hinged to the outer edges of said back-sections, rock-shafts journaled at the junctions of said covers and back-sections and carrying filing-pins e and tubular filing-pins e adapted to telescope by turning them into alinement across the back and forcing the back-sections together, and to be separated to assume upright positions by spreading apart said back-sections, guideflanges at opposite ends of one of said plates to receive the corresponding ends of theother plate, racks in said guide-flanges, and connected cog-wheels pivoted on said other plate to engage said racks, substantially as described.
